SUBCALIBER non REVOLVERS.

Specification of Letters Patent. Application filed December 27,1909. Serial No. 534,917.

Patented Aug. 30,1910.

Be it known that I, EDWAR B. Ynminn, citizen of the United States, residing at Fort Stevens, in the county of Glatsop and State of Oregon, have lnvented certain new and useful Improvements in Subcalibers for Revolvers, of which the following is a specification.

My invention relates to sub-caliber attachments for fire arms, and more particularlyx'to a device of the above character which is adapted to be used in connection with revolvers.'

An important object of my invention is to provide sub-caliber attachments capable of beingjquickly and conveniently applied to any ordinary revolver, which attachments will enable a marksman of'a small caliber in a revolver constructed to carry a cartridge of large caliber, thereby not only economizing 1n ammunition but rethe explosion and enabling a marksmanjto become familiar .with a certain weapon ;and practice .inplaces which would otherwise not be available."

A furtherobject of .my invention isto so construct the sub-caliber attachment that ducing the noise of .the same will not necessitate any alteration to "the weapon to which it is applied, and furthermore, to sojconstruct' the attachment as to insure accuracy "of fire.

A further object' f 'of my. invention isto provide asub-caliber attachment for a revolver, so constructe applied to the revolver, the rotation of the cy inderof the revolver will not be interferedwith, whereb. marksmen may practice.

IlIlVGIltlOlLGOHSlSlZS of the arrangement of parts to be hereinafter described.

In the accompanying drawings, forming a part of the specification, and in which like numerals are employed to designate like the revolver, and showing parts of 'myjdeto use a cartridge 1 d that when the same is vice in section and arranged within the chamber of the cylinder. Fig. 5 is a plan view of one end of the sub-ejector. Fig. 6 is a plan view of the opposite end of the sub ejector. Fig. 7 is an end view of the subcylinder arranged within the cylinder of the revolver.

In the drawings, I have illustrated my invention as applied to a forty-five caliber 1 Golt revolver.- The revolver comprises generally a body frame 1, within which is rotatably mounted a cylinder 2. The cylinder 2- is slidably mounted upon an axial pin 3, which .is slidably and rotatably mounted within the frame 1. At one end of the axial pin 3 is arranged a projector provided with a plurality of curved openings, which are arranged to aline with the corresponding ends of the usual chambers which are formed in the cylinder 2.- In Fig. 4:,a portion of the-extractor is illustrated at i and one of the chambers of the cylinder 2'is illustrated at 5 The revolver further comprovided with the usual prises a barrel 6,

sight-point '7, arranged at its free end.- As

no claim is made to the revolver itself, it is thought that the brief description of the same'is sufiicient to illustratethe manner in which my improved sub-caliber device is applied thereto.

Within the chamber 5, of the cylinder 2,

is arran ed a sub-cylinder 8, which is slightly rusto-conical in shape and is provided with a longitudinal cylindrical open ing 9. Each of the chambers 5 f'the cylinder -2' are slightly frnstosconical in shape and decrease in size toward the barrel-of.

the revolver. By this construction the subcylinder 8 may be inserted within the chamher 5 and held therein by frictional engagement. As illustrated in. Fig. 4, the of the sub-cylinder 8 is arranged flush with the far end of the cylinder 2, and the near end of the sub-cylinder 8 terminates within the chamber 5 at a point considerably re moved from the near end of the cylinder 2. As illustrated in Figs. 4 and 7, thenear end of the sub-cylinder 8 is provided, with a circular recess 10,, which surrounds the near end of the cylindrical opening '9 and is larger than said cylindrical opening. The

s'ubQcylinder 8 is farther provided .at its near end with a cut-out portion 11, which extends from the periphery of the sanie to' a point below the circular recess 10, as clearly far end I illustratedin Fig. 4. 'As illustrated in Fig.

far end a cylin er 8, and the flan ed end or rim 13, of

the cartridge 12 fits within the recess 10 but opening 9. Within is too large to enter the the near end of the opening 9 is arranged a sub-projector comprising a cylindrical body portlon '14, having a peripheral flange 15 at its near end, said flange being un ercut asat 16. It will be obviousfrom this construction that the an ordinary forty-five caliber cartridge. he extractor 4 is arranged under the flange 15, as illustrated in Fig. 4, and it is obvious that when the extractor 4;. is moved away from the cylinder, as is customary in removin empty shells from a Colt revolver, thesu ro ector 14 will accordin 1y removed rom the cylinder'2. The'su -projector 14 is provided with a central longi tudinal cyhndrical opening 17, within which is longitudinally slida ly mounted a cylindrical plunger 18-, carrying u on its ointed projection 19. T e rojection 19 is arranged adjacent the periphery of-th may firefrim-firmg cartridges. It is-well knownthat cartridges of small caliber, such "d as twenty-two caliber, are generally made to and I have therefore illusfire at the .rim,

' trated thepointed projection 19, arranged .to fire rim-firing cartrid ger, when it is desiredto use center-firing cartridges. I A i f The sub-projector 14 is provided with a longitudinal groove 20, which communicates cartridge12. The near end of the spring 21 is anchored as at 23 in the groove 20, by any suitable means; It is obvious by reference to Fi 4' that the spring 21 is capable of latera movement within the groove 20 and is prevented from having longitudinal movement; The far end of the spring 21 is beveled, so that the same may be-forced outwardly by the rim of a cartridge when the sub-projector is being inserted within the chamber 5. After the hook-like portion 22 has passed the rim of the cartridge, the same will sprin behind the rim, as illustrated in Fig.4, whereby when the'sub-projector is removed from the-cylinder 2, said sub-projector will accordingly remove the cartridge12. v

The plunger 18 is provided u on its periphery with a longitudinally is osed groove 24, within WhlCh is arrange the sub-projector 14 is somewhat similar in construction to the shell of bayonet slot is adapted to scribed, are to be chambers. vplunger inorder that the same es, but it is to be understood that I may F ace the projection v 19 at the center' of the r end of the plan 2, In a device of the cured within a chamber' inner end of a screw 2;, tapped through the'body portion of the sub-projector 14, whereby the longitudinal movement ofthe plunger 18 is limited;

In connection with the parts of my device so far'described I employ a sub-barrel 26, which 'is cylindrical and ada ted to fit snugly'withm the barrel 6 of t revolver. The far end'of the barrel 26 is provided with a cylindrical cap 27, provided uponone side thereof with a bayonet slot 28 for the rece tion of the sight 7, of the revolver. T e cap 27 is arranged upon the far end of the barrel 6, and is illustrated in Fig. 3 the revent the lon itudinal displacement of t e ca 27 and ts barrel 26. Upon the lower sidb of the cap 27 is formed a boss 29-, through which extends a screw 30, adapted to engage the bar- 'rel 6, and clamp the cap 27 agamst rotation.

The near, end of the sub-barrel 26 is arranged flush with the near end of the barrel 6, as clearly-illustrated in Fig. 2.

It is to be understood that a sub-cylinder and sub-projector similar to those above de:- arranged ineach of the 0f; the cylinder 20f the revolver.

It is obviousbfi the construction hereinabove described, t at the employment of my evice does it not efiect the =.1'=otation of the cylinder 2,,whereby said (i linder .ma be loaded with a. plurality a; cartridges. The Q eration of the Colt revolver 1s unafiecte ,by the employment of mydevice upon the same, and it is deemed unnecessary to describe the operation of'the revolver.

tion with my device forthe sake. of illustra tion only, and that I do not restrict myself to the' use of my device upon this revolver alone, for the same maybe applied just as well to the ordinary revolver. j

Having' fully described my invention, wha't claim is':- 1.
